Clinical symptoms of acute myocardial infarction

The clinical symptoms of acute myocardial infarction very different, about 1 / 3 of the onset Jizhou, very serious, not until hospital had died in hospital; 1 / 4 to 1 / 3 of patients with no obvious symptoms, are asymptomatic Of myocardial infarction, or very light did not cause symptoms in patients with attention, at the end of the hospital, about 1 / 3 1 1 / 2 of the patients were hospital treatment. Initial symptoms of acute myocardial infarction incidence vary, the most common for the pain. Therefore, when the incidence of different symptoms start to understand, timely diagnosis and treatment of diseases of great significance. (1) to pain as the initial symptoms. About 70 percent of the patients with acute myocardial infarction as the main symptoms of pain, and this cell of severe angina attack more general and long-lasting. In addition to the pain site sternum, heart and other mainly former district, about 10 percent of patients could be affected Jiantu Jiaotong under or on the abdomen, easily mistaken for stomach pain. Not a typical site is also available in right chest pain, mandibular, neck, teeth, a rare head, thigh and lower limb pain toe. (2) to suddenly start for the symptoms of syncope. Common in the early acute inferior infarction, higher vagal tone of the patients, the onset occurred in more than 30 minutes. Serious sinus bradycardia, or a high degree atrioventricular block, Jiman heart rate, blood pressure lowering, patients may suddenly syncope. (3) to sudden death as the initial symptoms. Is the incidence of ventricular fibrillation, for the performance of sudden death, occurred in the hospital. (4) with acute left ventricular failure for the incidence outstanding performance. Patients with sudden onset of the initial performance of pulmonary edema, without prior warning, some a few hours or a few days ago, a precursor of angina symptoms. McGREGOR incidence chest pressure nausea, breathing difficulties asphyxiating, Duanzuo breathing, a respiratory noise, the lungs can be heard and blisters on the characteristics of sound, 1,10 white or pink bubble phlegm, sweat, cyanosis unknowingly generally more pain, or Clearly overshadowed by breathing difficulties. Left ventricular failure to a lesser extent, lung congestion, the more common clinical, and more pain symptoms. Patients have paroxysmal difficulty in breathing, asthmatic breathing, bronchial asthma Ming-Liang Fei, often misdiagnosed as bronchial breathing. (5) to highlight the onset of shock symptoms. Patients are weak, sweat collapse, such as the slide down from the seat, fell standing position, or a transient loss of consciousness. Because blood is too low cardiac output caused by cerebral ischemia, who was killed extremely serious. Level slightly light, a cold sweat, dizziness, limb Humidicool, pallor or grey cyanosis, Xiruo pulse, systolic blood pressure less than 10.7 kPa (80mmHg), Niaoshao or urine.
